In October 2024, CEPI announced that it is awarding funding of up to £3.7 million to support researchers at the University of Sheffield as they seek proof-of-concept for RNAbox. RNAbox is a specialised process designed to scale up the production of mRNA vaccines at regional vaccine sites. It is “easily adaptable and automated”, with the potential to improve global pandemic readiness by enabling increased equitable access to various mRNA vaccines, as and when needed. It also could help speed up responses to future emerging outbreaks.
Addressing mRNA challenges
mRNA vaccines be “more rapidly tailored” to specific diseases or variants, and the technology “holds promise” for different illnesses, including emerging infectious diseases. However, mRNA vaccines are “expensive to manufacture at a high product quality” and require complex cold-chain storage and transportation infrastructure. This makes them “extremely difficult to deliver to remote areas or low-resource settings”.
The RNAbox presents a potential solution to these challenges through its bespoke manufacturing process, designed to overcome the need to deliver the vaccine by facilitating local manufacture at small production sites. The process will run continuously to create between seven and ten times more mRNA at a time and enable more efficient use of raw materials. RNAbox uses digital-twin technology, in which a virtual replica of the vaccine manufacturing process is modelled on a computer in real-time with smart sensors collecting data on the physical product.
CEPI’s interest
CEPI states that the “fast, optimised vaccine production is critical to the 100 Days Mission”. The investment will explore applying the technology to vaccine development for CEPI priority pathogens, including the viruses that cause deadly diseases like Ebola, Lassa fever, MERS, and Nipah. Ingrid Kromann, Acting Executive Director of Manufacturing and Supply Chain at CEPI suggested that the University’s “versatile” technology “builds on the ‘vaccine revolution’ experienced during the COVID-19 pandemic”.
“It aims to overcome a number of scientific hurdles which resulted in poorer countries facing devastating vaccine inequity by helping to make high-quality, low-cost vaccines quickly and easily close to the source of an outbreak.”
Dr Zoltán Kis, School of Chemical, Materials, and Biological Engineering at the University of Sheffield, reflected on the “importance of being prepared” with the “necessary tools”.
“We need to tackle outbreaks equitably around the world, as diseases can spread across country borders.”
The RNAbox will “accelerate the development of new vaccines” and “mass-manufacturing against a wide range of diseases”.
“This transformative technology can also be used to develop much-needed vaccines against a range of unmet needs during non-epidemic/pandemic times. In case of a new epidemic/pandemic, the RNAbox can be quickly adapted to produce vaccines to tackle outbreaks. This will enable vaccine development and manufacturing capacity locally in countries around the world to serve local needs.”
The researchers will work with vaccine manufacturers in low- and middle-income countries to ensure the technology is fit-for-purpose in lower-resource settings.
At the Congress in Barcelona this month we will hear from experts who are revolutionising mRNA vaccine production to ensure products are accessible. Join us there to learn more, and don’t forget to subscribe to our weekly newsletters here.
